unbibiumIf the human race lived in space for 700 years on a cruise ship, they would not become progressively fatter.
First of all, if people are going on a cruise, and there are enough resources to keep people fat, then there are going to be at least a few people who work out and stay in shape. They'll have the same selection advantages they have on Earth, even if they have no survival advantage.
The economy of a cruise ship that's been in space for 700 years would probably dictate the evolutionary pressures. I can see many where the humans get weaker, but not necessarily larger, unless the ship consistently takes in more resources than it expends. I'd go as far as to say that, on any generational spaceship, people would get smaller over time.
amirite?
